 ### Deferred Checkpoint — Phase 15 Plan 15-03 Task 2 (human-action)
 
 Operator must update Gitea branch protection on `main` AFTER this branch merges and `CI / gate` has reported at least once:
+
 - Set required status checks to EXACTLY: `CI / fast-checks` + `CI / gate`
 - REMOVE: `CI / api` + `CI / harness` (now conditionally skipped on doc-only PRs, gated via the always-running `CI / gate`)
 - CLI option (login Bergerhouse): `tea api --method PATCH repos/luckberg/familysync/branches/main/protection --data '{"status_check_contexts":["CI / fast-checks","CI / gate"]}'`
